Method for Calculating the Efforts on the Bearings and the Shaft of a Soil Axial Pump

The article presents a method for calculating the efforts on the bearings and the shaft of a soil axial pump located on the frame of a dredger suction device. The article considers the abrasive wear of the impeller during operation, which increases the centrifugal force and causes increased shaft bending, as well as the axial force on the pump impeller created by the pump head and the components of the weight of the shaft and impeller when the frame is tilted.
